VEHICLE-TIRE.

To all whom it may conce-rn:

Bc it known that I, ROBERT M. MERRI- MAN, citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Vehicle-Tires, of which the following is a specification.

This invention is designed to reinforce tires of the yielding or soft tread type in a manner to revent creepinv or separationof the materiali forming the tire from the reinforcement. It is common to embed s. Wire, metal stri or cable in the rubber or like material o e tire, but in practice such wire strip, cable or like reinforcement separates from the material and permits the latter to creep or the reinforcement cuts through the materiel.

The present invention aims to obviate the objections herein noted and to combine with a tire a reinforcement which will maintain e fixed relation to the material of the tire under all conditions.

This invention contemplates a reinforcement embod 'ing motel and textile strands woven toget er in a way to completely inclose the metal strands, and subse uently coating the reinforcement with a i'ubtlier cement and then vulcanizing said reinforcement after it has been embodied or molded into the tire so as to become in effect a part thereof thereby effectunlly preventinv creeping of the material of the tire or tie cutting of the reinforcement through the tire when the latter is subjected to stress such as resulting from usage. Inasmuch as the tire in its finished state is the result of a definite process, the two are apparently inseparable; hence the invention may be said to consist of the tire and the process of constructing thc saine.

In thc accompanying drawings forming o part of the specifications: Figure 1 is a per'A spective view of s portion of a tire embodying the invention. Fig. 2 is a detail view of the reinforcement.

The invention is adapt-able to any form of tire solid, cushion or vneumatic, and to tires for heavy or light loaf. s. The reinforcement may be continuous or in straight lengths nceording as the tire is of annular formation or provided in lengths. The tire 5 may embody any number of reinforcements and the latter may be dis osed or arranged within the tire to obtain t e best results aceordin to the special purpose for which the tire is esi ed and the nature of the rim structure 6 o the wheel for which the tire is adapted.

The reinforcement 1 in general construction appears similar to a rope or cable and comprises metal strands 2 and textile strands 3. The metal strands are intended to sustain linear tension whereas the textile strands being interwoven with the metal strands, give the necessary bulk, and moreover absorb the rubber cement, Whereb the vulcanizing causes the material of the tire to cling to the textile portion of the reinforcement in s. manner to prevent creeping of the materiel or the cutting of the reinforcement throii h the material. The metal strands 2 and t e textile strands 3 are interwoven and twisted together to provide a. cord or rope of ordinary forni, the metal strands be' v completely enveloped by the textile stran s and the latter being so interwoven with the metal strands as to prevent ossible separation of the two sets of stranifg. As shown on the drawin the metal strands are arranged in airs, t ie strands of each individual pair being twisted together and the various pairs being also twisted together and interwoven with the textile strands to provide the reinforcing cable. The reinforcement is dipped into, or otherwise coated with rubber cement 4 which penetrating the textiie portion of the reinornement, becomes practically inseparable therefrom. In formi forcement is eiiibeddiil therein and is vulcanizcd thereby cousin the rubber of the tire to become practica y inse arable from thc reinforcoiiu-ntg hence preclin ing creeping of the iiinteriiil or tho cutting of the reinforcement through the material of the tire.

Having thus described thc invention, what is claimed as new is:

The licreiiidescribed reinforcing cable for rubber tires, the scid cable ('oiisistin` of ii plurality of metal and textile stre-iii s, the metal strands boing twisted together and the the tire, the reintextile strands being twisted and interwoven In testimony whereof I ax my signature s? as tlolcotrgpletely cover1 the lrlnetal ttreanda, in presence of two witnesses.

t te ca e lng saturate wlt a ru r cement which penetrates the textile strands so ROBERT M' MERRIMAN' [L s'l 5 that when the cable is embedded and vuloan- Witnesses:

ized in the tire the reinforcement and tire are JonN ScnLAn,

practically inseparable from each other. W. C. MCKAIN.
